文摘This text intends to extract K+ by digestion of sample soil in 005mol/L HCl+00125mol/L H2SO4 to determine its density in the digestion liquid with low pressure ion chromatography.Keep 14m mol/LHNO3 in mobility, add 100μL sample digestion liquid, then determine the content of K+ throung conduction test.Applying this method to the determination of K+ in the actual sample soil,the RSD% is 017%,which conforms with the proposed value and shows good relevance.
